Solution

The correct option is C Selaginella and Salvinia
Heterospory is the production of spores of two different sizes and of two different developmental patterns -smaller male or microspores and larger female or megaspores. Heterospory is the most important evolutionary development in vascular plants because it has ultimately led to seed development, e.g., Selaginella, Salvinia, Azolla, etc.
So the correct option is C.
